Botanical Identification

Ecology

The ecology of Agrimonia coreana is characterized by its preference for specific montane environments, primarily thriving within forest ecosystems, open meadows, and shrubberies. It occupies a distinct altitudinal niche, with its distribution spanning an elevational range that begins at 500 m AMSL and reaches a maximum of 800 m AMSL. Within this vertical distribution, the species maintains an average elevational range of 650 m AMSL, reflecting its adaptation to the moderate climatic conditions found in these mid-elevation habitats.

Elevational range max:

800 m AMSL

Elevational range mean:

650 m AMSL

Elevational range min:

500 m AMSL

Habitat :

forest, meadows, shrubberies

Life history

The life history of Agrimonia coreana is characterized by its status as a perennial species, allowing it to persist through multiple growing seasons. As a perennial plant, it undergoes a recurring cycle of vegetative growth and seasonal transitions, establishing a stable presence within its natural habitat. This long-term lifecycle enables the plant to develop robust root systems and accumulate the necessary energy reserves to support repeated flowering and seed production cycles over several years, rather than completing its entire biological process in a single season.

Physiology

The physiological characteristics of Agrimonia coreana are closely linked to its foliar morphology, which plays a critical role in its metabolic processes and surface area optimization for photosynthesis. The leaf dimensions exhibit significant variability, with leaf lengths ranging from a minimum of 2 cm to a maximum of 6 cm, while maintaining a mean length of approximately 4 cm. This longitudinal variation is complemented by a corresponding breadth in the leaves, where widths fluctuate between a minimum of 1.5 cm and a maximum of 3 cm, resulting in a mean width of 2.25 cm. These specific measurements indicate a controlled growth pattern designed to balance light absorption and transpiration rates, ensuring efficient nutrient transport and physiological stability across its vegetative structures.

Reproduction

The reproduction of Agrimonia coreana is characterized by a specific flowering period and the development of small, consistent fruit structures. The flowering phase is concentrated in the month of July, serving as the primary window for its reproductive cycle. During this time, the flowers exhibit a relatively small size, with lengths ranging from a minimum of 0.7 cm to a maximum of 0.9 cm. Following pollination, the plant produces fruits that are highly uniform in their dimensions; the fruit length remains constant at a mean, minimum, and maximum of 0.5 cm, while the fruit width is consistently 0.4 cm, showing no variation between its minimum, mean, and maximum measurements.
